What Should a Cross-Country Runner Eat?

May 19, 2025

Proper nutrition is crucial for anyone with an active lifestyle. What you eat can make a big difference in your performance and recovery. A cross-country runner’s meal pattern should focus on fuel with the right mix of macronutrients and micronutrients. While every runner’s ideal ratio is different, it’s essential to experiment with these nutrients and find what works for your body.

Whether you are a seasoned athlete or just starting, understanding nutrition for runners is the key to reaching your goals while doing what you love.

Macronutrients for Runners

The main macronutrients or “macros” are carbohydrates, fats and proteins. These are the essential forms of sustenance that fuel your body, which is especially important to runners. Balancing your macros can help you maintain energy levels, hit that personal best and speed up recovery time. 

Why Are Carbohydrates Important for Runners?

Distance runners rely on carbohydrates as their primary source of energy. Your body needs enough carbs to store in your muscles and liver as glycogen and use it when you exercise. When these stores are too low, you are more likely to hit a wall or burn out during training. In your active lifestyle, it’s a good idea to fill your plate with half or a third of these foods and fuel your endurance:

  • Whole grains such as quinoa, oats and brown rice
  • Whole-wheat products like whole-grain pasta, toast and farro
  • Fruits like bananas, mangos and apples — any fruits are good fuel
  • Starchy veggies like potatoes, peas, winter squash or corn

Why Are Fats Important for Runners?

Fats are a secondary energy source, crucial for sustaining your long-distance endurance and supporting cell function. Make sure each meal or snack includes some of these foods to get the best healthy fats:

  • Nuts like pistachios, macadamia nuts, cashews and almonds
  • Seeds like pumpkin, chia or sunflower seeds
  • Omega-3 fatty acids in fish like salmon, sardines or anchovies
  • Avocados
  • Olive oil, avocado oil and sesame oil

Why Is Protein Important for Runners?

Proteins help repair muscles and tissues that are damaged during intense workouts. They’re an essential macro for your recovery, allowing you to come back stronger for your next training session. Aim to fill a quarter of your plate with protein:

  • Lean meats like fish, chicken, turkey and pork
  • Eggs
  • Beans, including soy, black and kidney beans
  • Nuts and nut butter like walnuts, cashews and almonds
  • Dairy products like milk, cheese, cottage cheese and yogurt

Micronutrients, Vitamins and Minerals for Runners

You need small amounts of micronutrients like vitamins and minerals to help prevent injuries, support your recovery and maintain energy levels. Fruit and vegetables are your main sources of antioxidants, minerals and vitamins. Eating the right mix of these foods is key to keeping your body healthy and recovering faster from endurance training.

Vitamins

Vitamins are a crucial part of any meal pattern for long-distance runners, as they help with energy production and recovery from intense training. Key vitamins include:

  • Vitamin D: Vitamin D works with calcium to help your body maintain its bone mineral density, reducing the risk of stress fractures. Try fortified dairy products, orange juice, almond, soy, or rice-based drinks, as well as eggs, tuna, and salmon to help you get enough vitamin D in your meals. Sun exposure is best, though — up to 30 minutes a day, between 10 a.m. and 4 p.m. at least twice a week, gives you what you need.
  • Vitamin B: Your B vitamins, found in meat, eggs and whole grains, help convert food into energy.
  • Vitamin C: Vitamin C keeps your immune system strong and helps with iron absorption. Citrus fruits, tomatoes and berries have a high vitamin C content.

Minerals

Minerals help cross-country runners maintain hydration, prevent cramps and support muscle function. Ensure your diet includes these minerals:

  • Iron: Iron carries oxygen to your muscles. A deficiency can lower your hemoglobin levels, affecting your blood oxygen. You may feel abnormal fatigue, dizziness upon standing and weakness. The best sources of this mineral include fortified cereals, red meat, beans, and dark leafy greens like kale and spinach.
  • Calcium: Leafy greens, dairy, fortified drinks, edamame and canned fish with bones — like sardines — contain calcium, which supports bone strength. Not getting enough calcium can increase your risk of stress fractures.
  • Electrolytes: Electrolytes — such as sodium, magnesium and potassium — are present in fruit, dairy, veggies and sports drinks. You will find this in source

Timing Your Meals and Snacks

Whatever you choose to fuel your run with, try these products during training to make sure they work well for your body’s needs during a competition. Doing so will help you determine what works best with your body, how easy it is to consume while you run and what you enjoy while out on the road or trail. 

What to Eat Before a Cross-Country Race or Run

If you have a serious race coming up, try carb-loading with pasta, rice or white bread between 48 and 72 hours before your race to shore up your body’s glycogen stores. For example, you can shift from loading a third of your plate with carbs to filling half your plate. You can also add some fruit, pretzels or granola bars as sides to your meals, drink more juice or consume more dairy products.

For training or competitive runs, fill a plate with half carbs, a quarter of protein and a quarter of fruits or veggies a couple of hours before your run. During this meal, avoid high-fiber foods like salads or raw veggies and high-fat foods like red meat, creamy sauces and fried foods, as they can cause gastrointestinal (GI) upset.

You can fuel with 30-60 grams of carb-rich snacks, like applesauce, animal crackers, bananas or granola bars, 30 to 60 minutes before your run. Stick to something easy to digest, like a fig bar, applesauce, bananas or crackers. Bring some glucose boosters with you for long runs, especially if you are running a marathon or more. These will fuel you on the go.

In addition to sports drinks or gel tubes, you can try cross-country snack ideas like fruit snacks and simple carbs like jelly beans, raisins or maple syrup sachets. You should have 60 grams of carbs per hour of your race.

Steer clear of high-fiber foods and anything spicy or overly high in fat. These foods can cause GI stress, leading to some less-than-ideal consequences during your run. 

What to Eat After a Cross-Country Race or Run

You might not feel hungry after your race or run, but your body needs to replenish its stores and support recovery. Rehydrate with water and electrolytes, refuel with healthy carbs and eat 20 to 30 grams of protein to rebuild those muscles. Grab a snack or light meal with protein and complex carbs within two hours after your run. Here are some ideas for perfect post-race snacks:

  • A smoothie or protein shake
  • Eggs on toast with some avocado or fruit
  • Peanut butter and a banana with low-fat chocolate milk or Greek yogurt
  • Whole-wheat or chickpea pasta with lean meat and broccoli
  • A sandwich with turkey and cheese on whole-wheat bread with a side of fruit
  • A bean and cheese burrito in a whole-wheat wrap
